Answer 1

Answer:

Explanation:

Hi mate

The mass of a non-volatile solute of molar mass 40 g /mol that should be dissolved in 114 g of octane to lower its vapour pressure by 20% is 10 g. Let w g of the non-volatile solute is used. Its molar mass is 40 g/mol. The number of moles of non volatile solute =40w=0.

Answer 2

Answer:

The mass of a non-volatile solute of molar mass 40 g /mol that should be dissolved in 114 g of octane to lower its vapour pressure by 20% is 10 g.
